Combining multiple classifiers to obtain improved performance over the individual classifier has been a widely used technique. The task of constructing a multiple classifier system(MCS) contains two different Issues how to generate a diverse set of base-level classifiers and how to combine their predictions. In this paper, we review the characteristics of existing multiple classifier systems : Bagging, Boosting, and Slaking. For document classification, we propose new MCSs such as Stacked Bagging, Stacked Boosting, Bagged Stacking, Boosted Stacking. These MCSs are a sort of hybrid MCSs that combine advantages of existing MCSs such as Bugging, Boosting, and Stacking. We conducted some experiments of document classification to evaluate the performances of the proposed schemes on MEDLINE, Usenet news, and Web document collections. The result of experiments demonstrate the superiority of our hybrid MCSs over the existing ones.

Background: In 1997 the Korean Association of Medical Journal Editors (KAMJE) instituted a program to evaluate member journals. Journals that passed the initial evaluation were indexed in the KoreaMed. Here, we report changes in measures of quality of the KAMJE member journals during the last 20 years. Methods: Quality measures used in the study comprised 3 assessment categories; self-assessment by journal editors, assessment of the journals by KAMJE reviewers, and by Korean health science librarians. Each used detailed criteria to score the journals on a scale of 0 to 5 or 6 in multiple dimensions. We compared scores at baseline evaluation and those after 7 years for 129 journals and compared improvements in journals indexed vs. not-indexed by the Web of Science (Science Citation Index Expanded; SCIE). Results: Among 251 KAMJE member journals at the end of 2015, 227 passed evaluation criteria and 129 (56%) had both baseline and 7-year follow-up assessment data. The journals showed improvement overall (increase in median [interquartile range; IQR] score from baseline, 0.47 [0.64]; 95% confidence interval [CI], 0.44-0.61; P < 0.001) and within each category (median [IQR] increase by editor's assessment, 0.17 [0.83]; 95% CI, 0.04-0.26; P = 0.007; by reviewer's, 0.45 [1.00]; 95% CI, 0.29-0.57; P < 0.001; by librarian's, 1.75 [1.08]; 95% CI, 1.77-2.18, P < 0.001). Before the foundation of KAMJE in 1996, there were only 5 Korean medical journals indexed in the MEDLINE and none in SCIE, but 24 journals in the MEDLINE and 34 journals in SCIE were indexed by 2016. Conclusion: The KAMJE journal evaluation program successfully contributes improving the quality of the member journals.

The purpose of the study was to identify available evidence related to physical activity interventions that were effective to improve health-related physical fitness levels of children and youth with disabilities. Studies were accumulated from multiple databases (i.e., ERIC, Child Development & Adolescent Studies, MEDLINE, SPORTDiscus with Full Text, and CINAHL Plus with Full Text). From the initial process, 1195 articles were identified and of those, 13 studies (n = 13) were analyzed. Based on the results, community-based physical activities were the most common environment of interventions followed by school-based and home-based. Further, the most improved health-related physical fitness outcomes were muscular strength, muscular endurance, and cardiorespiratory endurance while limited evidence on weight reduction was available. There is a need for more research on physical activity intervention which particularly improves health related physical fitness of children and youth with disabilities.

The purpose of this research is to meta-analyze on a comparative basis interventions for preventing falls by the elderly in their 70's and 80's in the eight countries. Eleven studies conducted by RCT were found via Medline in Ovid, PsychInfo and Cochrane Database of Systematic Reviews. Use of Review Manager shows that interventions in the 70's group are effective (OR=0.65, 95%) but that those in the 80's group are not (OR=1.57, 95%). Furthermore, the effectiveness of the 70's treatment group is not durable. This paper has three policy implications: First, new intervention programmes for preventing falls by the 70's group should be developed toward increasing durability. Second, existing programmes for the 80's group should be amended to enhance effectiveness. Lastly, new programmes that include cognitive-behavioural components should be designed for elderly individuals suffering from mental diseases.

Objective : The purpose of this study is to confirm the basis for the effectiveness of sleep intervention for dementia progression. Method : PsycINFO, CINAHL, MEDLINE, PubMed, Science Direct, PEDro, Cochrane library was used to search for published papers from 2000 to 2017 using dementia, sleep, and randomized controlled trials (RCTs). Based on the results, author analyzed the papers that met the selection criteria. Result : Finally, five papers were selected. Among them, there were four papers showing that the effectiveness of the sleep intervention was not proven to be one. Conclusion : The results of this study can provide a basis for the sleep intervention effect of dementia patients. A program to actively intervene to prevent patients' behavior control and disease progression through solving sleep problems of dementia patients is needed.

The quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. Two pairs of reviewers assessed the quality of the SGAs and the credibility of subgroup claims using the 10 criteria developed by Sun et al. in 2012. The associations between the quality of the SGAs and the studies' characteristics including risk of bias, funding sources, sample size, and the latest impact factor, were assessed using multivariable logistic regression. Our search retrieved 3,401 articles of which 66 were eligible. The total number of SGAs was 177 of which 52 (29.4%) made a subgroup claim. Of these, only 15 (8.5%) were evaluated as being of high quality. Among the 30 SGAs that claimed subgroup effects using an appropriate method of performing interaction tests, the credibility of only 5 were assessed as high. None of the subgroup claims met all the credibility criteria. No significant association was found between the quality of SGAs and the studies' characteristics. The quality of the SGAs performed in chronic pain trials was poor. To enhance the quality of SGAs, scholars should consider the developed criteria when designing and conducting trials, particularly those which need to be specified a priori.

PURPOSE: This study analyzed the trends and characteristics of shoulder rehabilitation research through keyword analysis, and their relationships were modeled using text mining techniques. METHODS: Abstract data of 10,121 articles in which abstracts were registered on the MEDLINE of PubMed with 'shoulder' and 'rehabilitation' as keywords were collected using python. By analyzing the frequency of words, 10 keywords were selected in the order of the highest frequency. Word-embedding was performed using the word2vec technique to analyze the similarity of words. In addition, the groups were classified and analyzed based on the distance (cosine similarity) through the t-SNE technique. RESULTS: The number of studies related to shoulder rehabilitation is increasing year after year, keywords most frequently used in relation to shoulder rehabilitation studies are 'patient', 'pain', and 'treatment'. The word2vec results showed that the words were highly correlated with 12 keywords from studies related to shoulder rehabilitation. Furthermore, through t-SNE, the keywords of the studies were divided into 5 groups. CONCLUSION: This study was the first study to model the keywords and their relationships that make up the abstracts of research in the MEDLINE of Pub Med related to 'shoulder' and 'rehabilitation' using text-mining techniques. The results of this study will help increase the diversifying research topics of shoulder rehabilitation studies to be conducted in the future.
